BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates generally to tartaric acid functional compoundsthat can inhibit matrix metalloproteinases (MMPs), a disintegrin andmetalloproteases (ADAMs) and/or tumor necrosis factor alpha-convertingenzyme (TACE) and in so doing prevent the release of tumor necrosisfactor alpha (TNF-α), pharmaceutical compositions comprising suchcompounds, and methods of treatment using such compounds.

2. Description

Osteo- and rheumatoid arthritis (OA and RA, respectively) aredestructive diseases of articular cartilage characterized by localizederosion of the cartilage surface. Findings have shown that articularcartilage from the femoral heads of patients with OA, for example, had areduced incorporation of radiolabeled sulfate over controls, suggestingthat there must be an enhanced rate of cartilage degradation in OA(Mankin et al. J. Bone Joint Surg. 52A (1970) 424-434). There are fourclasses of protein degradative enzymes in mammalian cells: serine,cysteine, aspartic and metalloproteases. The available evidence supportsthe belief that it is the metalloproteases that are responsible for thedegradation of the extracellular matrix of articullar cartilage in OAand RA. Increased activities of collagenases and stromelysin have beenfound in OA cartilage and the activity correlates with severity of thelesion (Mankin et al. Arthritis Rheum. 21, 1978, 761-766, Woessner etal. Arthritis Rheum. 26, 1983, 63-68 and Ibid. 27, 1984, 305-312). Inaddition, aggrecanase (a newly identified metalloprotease) has beenidentified that provides the specific cleavage product of proteoglycan,found in RA and OA patients (Lohmander L. S. et al. Arthritis Rheum. 36,1993, 1214-22).

Metalloproteases (MPs) have been implicated as the key enzymes in thedestruction of mammalian cartilage and bone. It can be expected that thepathogenesis of such diseases can be modified in a beneficial manner bythe administration of MP inhibitors (see Wahl et al. Ann. Rep. Med.Chem. 25, 175-184, AP, San Diego, 1990).

MMPs are a family of over 20 different enzymes that are involved in avariety of biological processes important in the uncontrolled breakdownof connective tissue, including proteoglycan and collagen, leading toresorption of the extracellular matrix. This is a feature of manypathological conditions, such as RA and OA, corneal, epidermal orgastric ulceration; tumor metastasis or invasion; periodontal diseaseand bone disease. Normally these catabolic enzymes are tightly regulatedat the level of their synthesis as well as at their level ofextracellular activity through the action of specific inhibitors, suchas alpha-2-macroglobulins and TIMPs (tissue inhibitor of MPs), whichform inactive complexes with the MMP's.

Tumor necrosis factor alpha (TNF-α) is a cell-associated cytokine thatis processed from a 26 kDa precursor form to a 17 kd active form. SeeBlack R. A. “Tumor necrosis factor-alpha converting enzyme” Int JBiochem Cell Biol. 2002 January; 34(1):1-5 and Moss M L, White J M,Lambert M H, Andrews R C. “TACE and other ADAM proteases as targets fordrug discovery” Drug Discov Today. 2001 Apr. 1; 6(8):417-426, each ofwhich is incorporated by reference herein.

TNF-α has been shown to play a pivotal role in immune and inflammatoryresponses. Inappropriate or over-expression of TNF-α is a hallmark of anumber of diseases, including RA, Crohn's disease, multiple sclerosis,psoriasis and sepsis. Inhibition of TNF-α production has been shown tobe beneficial in many preclinical models of inflammatory disease, makinginhibition of TNF-α production or signaling an appealing target for thedevelopment of novel anti-inflammatory drugs.

TNF-α is a primary mediator in humans and animals of inflammation, feverand acute phase responses, similar to those observed during acuteinfection and shock. Excess TNF-α has been shown to be lethal. Blockingthe effects of TNF-α with specific antibodies can be beneficial in avariety of conditions, including autoimmune diseases such as RA (Feldmanet al, Lancet, (1994) 344, 1105), non-insulin dependent diabetesmellitus (Lohmander L. S. et al., Arthritis Rheum. 36 (1993) 1214-22)and Crohn's disease (Macdonald T. et al., Clin. Exp. Immunol. 81 (1990)301).

Compounds that inhibit the production of TNF-α are therefore oftherapeutic importance for the treatment of inflammatory disorders.Recently it has been shown that metalloproteases, such as TACE, arecapable of converting TNF-α from its inactive to active form (Gearing etal Nature, 1994, 370, 555). Since excessive TNF-α production has beennoted in several disease conditions also characterized by MMP-mediatedtissue degradation, compounds which inhibit both MMPs and TNF-αproduction may also have a particular advantage in diseases where bothmechanisms are involved.

One approach to inhibiting the harmful effects of TNF-α is to inhibitthe enzyme, TACE before it can process TNF-α to its soluble form. TACEis a member of the ADAM family of type I membrane proteins and mediatesthe ectodomain shedding of various membrane-anchored signaling andadhesion proteins. TACE has become increasingly important in the studyof several diseases, including inflammatory disease, because of its rolein cleaving TNF-α from its “stalk” sequence and thus releasing thesoluble form of the TNF-α protein (Black R. A. Int J Biochem Cell Biol.2002 34, 1-5).

There are several patents which disclose hydroxamate, carboxylate and/orlactam based MMP inhibitors.

U.S. Pat. No. 6,677,355 and U.S. Pat. No. 6,534,491(B2), describecompounds that are hydroxamic acid derivatives and MMP inhibitors.

U.S. Pat. No. 6,495,565 discloses lactam derivatives that are potentialinhibitors of matrix metalloproteases and/or TNF-α.

There is a need in the art for inhibitors of MMPs, ADAMs, TACE, andTNF-α, which can be useful as anti-inflammatory compounds and cartilageprotecting therapeutics. The inhibition of TNF-α, TACE and or other MMPscan prevent the degradation of cartilage by these enzymes, therebyalleviating the pathological conditions of OA and RA as well as manyother auto-immune diseases.

TACE activity is determined by a kinetic assay measuring the rate ofincrease in fluorescent intensity generated by TACE catalyzed cleavageof an internally quenched peptide substrate (SPDL-3). The purifiedcatalytic domain of recombinant human TACE (rhTACEc, Residue 215 to 477with two mutation (S266A and N452Q) and a 6×His tail) is used in theassay. It is purified from the baculovirus/Hi5 cells expression systemusing affinity chromatography. The substrate SPDL-3 is an internallyquenched peptide(MCA-Pro-Leu-Ala-Gln-Ala-Val-Arg-Ser-Ser-Ser-Dpa-Arg-NH2), with itssequence derived from the pro-TNFα cleavage site. MCA is(7-Methoxycoumarin-4-yl)acetyl. Dpa isN-3-(2,4-Dinitrophenyl)-L-2,3-diaminopropionyl.

A 50 μl assay mixture contains 20 mM HEPES, pH 7.3, 5 mM CaCl₂, 100 μMZnCl₂, 2% DMSO, 0.04% Methylcellulose, 30 μM SPDL-3, 70 pM rhTACEc and atest compound. RhTACEc is pre-incubated with the testing compound for 90min. at 25° C. Reaction is started by addition of the substrate. Thefluorescent intensity (excitation at 320 nm, emission at 405 nm) wasmeasured every 45 seconds for 30 min. using a fluorospectrometer (GEMINIXS, Molecular Devices). Rate of enzymatic reaction is shown as Units persecond. Effect of a test compound is shown as % of TACE activity in theabsence of the compound.

TACE inhibitory activities for representative compounds are shown in thetable below. K_(i) values greater than 1000 nM (1 μM) are designated asD class. K_(i) values between 100 nM (0.1 μM) and 1000 nM (1 μM) aredesignated as C class. K_(i) values between 20 nM (0.02 μM) and 100 nM(0.1 μM) are designated as B class. K_(i) values less than 20 nM (0.02μM) are designated as A class.

Example 1 General Synthesis of Tartrate Inhibitors

Two general routes exist for the synthesis of tartrate diamides fromamines. The first (Example 1) utilizes an acetonide-protectedmonoacid/monoester intermediate prepared from the commercially availableacetonide dimethyl ester using a literature procedure (J. Am. Chem. Soc.1978, 100, 4865-4872). In general either Example 1 or Example 2 could beused interchangeably, although Example 2 was found to be more preferredfor compounds that contained functional groups that were unstabletowards acidic deprotection conditions (such as 113).

A variety of amide bond coupling reagents were acceptable, includingHATU, CDI, EDC, DCC/HOBt, PyBrOP, polymer supported CDI with HOBt,polymer supported carbodiimide, and polymer supported EDC(PS-EDC) withHOBt. These coupling reagents could be used with a variety of bases,including triethylamine (TEA), diisopropylethylamine (DIEA). N-methylmorpholine, pyridine, dimethylaminopyridine (DMAP) and imidazole. Insome cases the excess amines in the peptide coupling steps were removedusing liquid/liquid extraction or polymeric scavenging resins such aspolymer supported isocyanate (PS—NCO) and/or polymer supported tosicacid (MP-TsOH). Unreacted acids could be removed using MP-carbonateresin or polymer resins containing basic functional groups such astrisamine (i.e. PS-trisamine), amberlite, or morpholine. Peptidecouplings were conducted in a variety of solvents, including DMF, THF,dioxane, acetonitrile. NMP, and DCM. These solvents can also be combinedin various proportions to optimize the reaction conditions. A lesspreferred but viable route using pentafluorophenyl (PFP) esterintermediates may be also utilized to prepare mono or diamides;preferred solvents for this approach should include THF. General peptidecoupling strategies, including PFP-based approaches, can be found inBodanszky & Bodanszky, The Practice of Peptide Synthesis, secondedition, Springer-Verlag, 1994.

Cleavage (saponification) of the intermediate methyl ester could beaccomplished under a variety of well-known conditions; including: aslight excess (1.1-3 equivalents) of base, KOH in methanol, LiOH inTHF/water, LiOH in methanol/water, and NaOH/THF/MeOH/water. Removal ofthe acetonide protecting group could be afforded using a variety ofacidic conditions, including TFA:water combinations (such as 80:20).

Part A:

To 2,2-dimethyl-[1,3]dioxolane-4R,5R-dicarboxylic acid monomethyl ester(1) (Musich, J. A.; Rapoport, H.; J. Am. Chem. Soc. 1978, 100,4865-4872) (500 mg, 2.45 mmol) in DMF (5 mL) was added2-thiopheneethylamine (316 μL, 2.70 mmol), DIEA (0.94 mL, 5.4 mmol) andHATU (989 mg, 2.60 mmol). The reaction mixture was stirred overnight andthe DMF was removed in vacuo. The residue was dissolved in EtOAc, washedwith water, saturated bicarbonate solution, 0.1 N HCl, and brine. Theorganic layer was dried over sodium sulfate and concentrated.Purification by column chromatography (SiO₂, 10% EtOAc/DCM) afforded 2as an oil (491 mg, 64%). ¹H NMR (400 MHz, CDCl₃) δ 7.17 (dd, 1H, J=1.2,5.2 Hz), 6.95 (dd, 1H, J=2.1, 5.2 Hz), 6.84 (d, 1H, J=2.4 Hz), 6.66 (bs,1H, NH), 4.72 (ABq, 2H, J=13.2 Hz), 3.84 (s, 3H), 3.65 (m, 1H), 3.57 (m,1H), 3.09 (t, 2H, J=6.4 Hz), 1.47 (s, 3H), 1.40 (s, 3H); HPLC-MSt_(R)=1.63 min (UV_(254 nm)); Mass calculated for formula C₁₄H₁₉NO₅S313.1, observed LCMS m/z 314.2 (M+H).

Part B:

To 2 (869 mg, 2.77 mmol) in THF (10 mL) was added 1.0 M LiOH (3 mL, 3mmol) and the reaction was stirred overnight at room temperature.

Example 2 Anhydride Route to Tartrate Diamide Inhibitors

A second general route to diamide compounds starting from an anhydrideintermediate is delineated below in Example 2. (+)-Diacetyl L-tartaricanhydride (48) is an article of commerce and reacts readily with avariety of amines to generate monoacid/monoamide intermediate. Thepreferred solvent for the ring opening is DCM; although DMF, THF ordioxane may also be compatible. The subsequent peptide coupling stepproceeds under a variety of standard conditions which are given forExample 1. The acetate groups can be removed using a variety ofconditions, including hydrazine/methanol, NaOMe in methanol,ammonia/methanol, lithium hydroxide/THF/water (saponification),potassium carbonate in methanol, or MP-carbonate. Often times thepreferred set of conditions for parallel synthesis is to use theMP-carbonate. It has also been observed that one or both of the acetateprotecting groups can be cleaved during synthetic transformationsinvolving nucleophiles, basic reagents, heating in protic solvents orexposure to organometallic reagents.

Example 3 Heteroaryl Biaryl Compounds

A compound precursor may be prepared such that the synthesis of directanalogs is facilitated. Examples of schemes for biaryl synthesis arelisted below. Aryl halides and ‘pseudo-halides’ (i.e. triflates) areknown to react with boronic acids under a variety of establishedconditions (Top. Curr. Chem. 2002, 219, 12-49). A variety of bases forthis reaction are known in the literature, including sodium carbonate,potassium carbonate, cesium carbonate, potassium t-butoxide, sodiumt-butoxide, TEA, DIEA, potassium fluoride, and potassium phosphate. Formost applications potassium phosphate was preferred and gave acceptableyields and chemoselectivity. A number of solvents have also been used inthe literature for Suzuki reactions, including THF, dioxane, NMP, DMF,DME, DMA, toluene, and water. In general we have found that THF ordioxane are preferred solvents. Solvents may also be mixed in variousproportions to enhance reactivity and/or chemoselectivity. Palladiumsources for this reaction are numerous as well, including Pd(TPP)₄,Pd(OAc)₂, PdCl₂(TPP)₂, PdCl₂(dppf), Pd₂(dba)₃. In general PdCl₂(dppf)was found to be a preferred palladium source.

Example 4 Thiophene-Benzyl Compounds

Pd-mediated Negishi-type couplings were an efficient way to generate aset of relevant compounds for this series where Ar was a phenyl ring.While a range of palladium sources are known we found that Pd(P^(t)Bu₃)₂was preferred. The reaction can be run in a variety of solvent systems,including dioxane, THF, or DMA. A preferred method utilized the solventfrom the zinc reagent, which was typically available as a THF stocksolution. Removal of the t-BOC group can be completed using a range ofacidic conditions including TFA/water, HCl in methanol, and HCl indioxane; all of which proceeded equally well with most reactionsubstrates. The reactions are typically concentrated and freeze-dried togive HCl or TFA salts. The Negishi reactions proceed comparably, and inmany cases better, when the amine was protected by a phthalimide. Thephthalimide protecting group could be removed by heating in ethanolcontaining hydrazine hydrate.
